To all whom, it may concern:

Be it known that we, GEORGE FrMONNIN and ANDREW J. C. MEOOHI, citizens of the United States, and residents of San Francisco, in the county of San Francisco and State of California, have invented a new and Improved Window-Screen, of which the following is a full, clear, and exact description.

One object of our invention is to provide novel, simple, and effective means for detachably connecting a framed window-screen with the lower sash of a window and for hanging the screen-frame in a receiving pocket formed in the wall of the building below the sill of the window therein having the improvement applied thereto, whereby the screen when con-- nected with the lower sash may be raised into position for service a corresponding degree when said sash is raised and be returned into the pocket when the'sash is lowered.

A further object is to provide novel and effective means for preventing the entrance of flies or other insects between the upper and lower sashes of a window when the lower sash is partially raised or the upper sash partly lowered.

To these ends the invention consists in the novel construction and combination of parts, as is hereinafter described, and defined in the subjoined claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is an inner side view of a window having the improvement applied and in position for service. Fig. 2 is an enlarged transverse sectional view substantially on the broken line 2 2 in Fig. 1. Fig. 3 is an enlarged detached perspective view of the main portion of the novel means for detachably connecting a window-screen with the lower sash of a window. Fig. 4 is a partly sectional View of novel details substantially on the line 4 4:

in Fig. 2. Fig. 5 is a detached perspective View of a novel device for preventing flies or other insects from passing into a room between partly-opened window-sashes. Fig. 6

is an enlarged end view of the device shown in Fig. 5, and Fig. 7 is a detached perspective view of a modified construction for the detachable connection between a lower sash of a window and a window-screen.

The invention is designed for application to may be in theform of a rectangular pocket C,

and, as shown in Fig. 2, a vertical slot 00 is formed in the sill A of the casement A in alinement with the pocket C, thus providing an opening in the window-sill that extends the full width of the easement between its side stiles. The window-sashesD E, that, as usual, are held to slide vertically in the stiles of the easement A, are spaced apart by the ordinary parting-strips which project from the stiles, so that the lower sash E is held to slide directly above the slot at.

In the pocket C the rectangular frame t of a fine -'meshed screen 4*" is loosely fitted, the 4 width and thickness of said frame adapting it to reciprocate in the slot (1 and traverse the grooves in the window-casement that accommodate the side edges of the lower sash E. Two bracket-plates 5 of equal dimensions and preferably having a width equal to the thickness of the screen-frame are provided for the detachable connection of the frame and sash, as is represented for one bracket-plate in Fig. 4.

To adapt'the bracket-plates for effective service and afford clearance for other parts hereinafter described, these plates are bent at b so as to dispose their upper portions in planes at one side of and parallel with'their lower portions, or, in other words, producing ofisets at said points 6. The lower portions of the bracket-plates 5 are secured upon the side edges of the screen-frame 4 at and near the top rail of said frame, which disposes the upper portions 5 of said plates above said top rail.

In the side edges of the lower sash E opposite rabbets c are formed at and near the lower transverse rail E of said sash, and,.as indicated at the left in Fig. 4, the upper portions 5 of the bracket-plates 5 slide into and occupy the rabbets 0 when the sash E is completely lowered, it being understood that the upper transverse edge of the screen-frame I is supported flush with the surface of the sill A when the screen-frame by its gravity is seated in the pocket C. In the lower transverse rail E of the sash E a perforation is formed at a suitable distance from the lower edge of the rail and parallel therewith, said perforation receiving a guide-tube 6, which may extend completely through the perforation, having its ends flush with the sides of the rabbets 0,

or two tubes may be employed that are of proper length and each be inserted in a perforation, as shown for one tube in Fig. 4. Two similar latch-bolts 7 are loosely fitted in the tube or tubes 6 and have similarly-beveled ends d, that in service may each be projected through a perforation 6, formed in the respective bracket member 5 and opposite the corresponding end of the guide-tube 6. It may here be explained that if the window is of considerable width the means employed for controlling the latch-bolts 7 may be duplicated, each device consisting of the following details: In the lower transverse 'rail E of the lower sash E, at a suitable distance from each side edge of said sash, a recess g is formed, these similar recesses being open at the side of the rail that is within the room. The recesses g are of such depth as to expose the upper side of the guide-tube 6 therein, and at a point in the guide-tube within each recess a vertical screw-hole is formed in the tube, which receives a screw it.

An expanding-spring it is placed in the tube 6 for contact with each screw it, and, as appears in Fig. 4:, where one spring is shown,

said spring seats upon the body of the screw with one end and at the opposite end is in con tact with the inner end of a respective latchbolt 7, the tension of each spring being adapted to press the latch-bolt it contacts with through a perforation 6 when the bolt is disposed opposite the perforation, which occurs when the sash E is completely lowered.

In each latch-bolt 7, near its inner end, one end of a pusher-arm 8 is secured, this arm, that may be bent into a substantially Z shape, passing at one end through a slot if, that is longitudinally formed in the guide-tube 6, the longer members of the pusher-arms projecting upward and parallel with each other when the parts of the device are assembled for service.

A face-plate 9 is provided for each recess g, said plates being flat, preferably rectangular planchets of sheet metal of such dimensions asadapt them to cover the respective recesses when secured in place by screws that may be inserted through perforations din the.

plates and thence into the sash-rail. A knob 10 is furnished for each face-plate 9, the knobs each having a reduced shank member it, that is fitted into a circular opening at the center of a respective face-plate, said shank having a threaded extension and a plain member projected beyond the thread, as is shown at Z in Figs. 2 and 3, this extension being either tubular, as shown, or solid, if preferred. A nut Z is screwed upon each threaded extension of a knob-shank 7t, and in the plain portion Z thereof an axial slot is formed for the reception of a yoke-plate 11. Each yoke-plate 11 is formed with flat parallel sides, a laterally-elongated body, and a tongue at, extended'from one side edge of the body, this tongue being fitted into the slot in the part Z of the shank in on each knob 10 and therein secured by a key or cross-pin 0. Ineach yoke-plate 11 a longitudinal slot 0 is formed, that receives the main or upper portion of a respective pusher-arm 8, which projects above the yoke-plate a suitable distance to insure its remaining in the slot when the yoke-plate is rocked by manipulation of the knob 10. The nut Z provides a collar for the proper rotatable support of the knob 10 and also serves as a supporting abutment for the tongue of the yoke-plate 11.

It will be seen that by simply lowering the sash E the latch-bolts 7, that were protruded, as shown at the left of Fig. 4 bydotted lines, will be pressed into the tube 6 by an engagement of their beveled noses with the upper transverse edges of the bracket-plates 5. This serves to. compress the springs if, the stress of which will project the beveled ends of the latch-bolts through the perforations e in the respective bracket-plates 5 when the windowsash E is closed and its lower edge is in contact with the upper edge of the screen-frame 4:.

The elevation of the lower sash E when connected with the screen-frame L and screen at will correspondingly raise the screen, and obviously the latter will prevent an entrance of insects intothe window at any elevation given to the lower sash.

When it is desired to release the windowsash E from the frame 4, this may be readily effected by simply turning the knobs 10, so as to rock the yoke-plates 11 into engagement with the pusher-arms 8, which will retract the latch-bolts 7, whereupon a slight elevation of the sash while the latch-bolts are held retracted will release the screen-frame and permit the window to be opened by elevation of the lower sash, the knobs 10 affording convenient handholds for such a purpose.

hen the improved screen is to be applied to a narrow window, the sashes of which are comparatively light, so that one knob 10 will enable the lower sash of the window to be raised and lowered, the construction of the device for retracting the latch-bolts may be slightly changed in relative arrangement of parts to adapt one knob and one yoke-plate for simultaneously retracting the bolts, this modified construction being shown in Fig. 7. In this case the guide-tube (indicated by the reference character 6) is slotted longitudinally at two points If equally distant from the center of length, as shown, and at said center a screw h is inserted through a transverse perforation in the tube and into the lower sash-rail, that the tube is located in, as before explained. Two similar coiled springs 7b are placed in the tubeone at each side of the screw 7L and in contact with it. Two slidable latch-bolts 7 are inserted into the respective ends of the guide-tube 6 and seat upon the ends of the springs if, the remaining ends of these latchbolts (not shown) having beveled ends normally projected somewhat beyond the corresponding ends of the guide-tube, as described with regard to the latch-bolts 7. In each latch-bolt 7, near its inner end, two pusherarms 8, similar to the pusher-arms 8, are secured by like ends and are first passed down through the respective slots 7?, and the main upright members of said arms, which are disposed parallel with each other, are spaced apart at an equal distance from the screw 5 A single face-plate 9", similar to the face-plates 9, is placed over a recess similar to the recesses 9, formed in the lower cross-rail of the lower sash, that supports the latch-bolts 7 A knob 10 is held to turn in a circular opening in the face-plate 9 by a collar-nut l screwed upon a shank extension of the knob, said extension having an axial slot wherein a tongue m on the yoke-plate 11, which is like the yokeplates 11, is'inserted and secured by a crosspin 0 or the like. The slot 0 in the yokeplate 11 is similar to the slots 0 in the yokeplates 11 and is of such length as will permit the free insertion of the pusher-arms 8 upward therethrough.

Assuming that the window-sashsuch as E, but of less widthis held to slide in a windowcasement that has its sill longitudinally slotted for the free reciprocation of a window-screen such as described, which when out of use is held in a pocket below said sill, and that the screen-frame is furnished with bracket-plates 5, having laterally-perforated members 5, that will loosely embrace the side edges of the window-sash, so as to dispose these perforations of the bracket-plates opposite the ends of the guide-tube 6 when the lower sash is closed, it will be evident that the act of closing the lower sash upon the sill of the casement will, as hereinbefore described, cause the beveled ends of the latch-bolts to enter the perforations formed in the bracket-plates 5 and latch fast to said bracket-plates so that the screen and window-sash are secured together, the elevation of the sash correspondingly moving the screen that covers the opening below the sash. When the lower sash is to be released from the window-screen, this may be readily effected by a partial rotation of the knob 10, which will correspondingly rock the yoke-plate 11 and draw the pusherarms 8 toward each other against stress of .the springs 7t, which will retract the latchbolts 7 and release them from the bracketplates 5, the knob 10 affording convenient means for the elevation of the sash.

As it is at times desirable that the lower sash of a window having the improved screen be raised partially, and, as is well known, if the lower transverse rail of the lower sash is not raised so as to meet the lower transverse rail of the upper sash, a free passage is left between the glazing of the sashes for the ingress of insects into the room. To prevent the entrance of insects between the windowsashes when the lower one is partly raised, a novel simple auxiliary protection is provided that when employed along with the improvements already described will efiect the exclusion of flies or other insects in a perfect manner without regard to the degree of elevation given to the lower sash, this coacting feature being represented in Figs. 1, 2, 5, and 6 and comprising the following details: A preferably plate-metal brush-head is formed of an elongated rectangular sheet of metal, which is return-bent at the center of width, thus affording two like clamping-leaves 12, that are integral with a tubulation 12 wherein a pintle-rod 12 is tightly held. The clamp ing-leaves 12 may have their free edges curved slightly outward and receive between them brush material 12, which may be bristles or two notches are cut, these notches permitting a looped member 7" on a bracket-plate 12 to loosely embrace the pintle-rod at each notch, thus affording a hinged connection for two similar bracket-plates with the pintlerod. Upon the normal lower side of each bracketplate 12 a leaf-spring 12 is secured by one end and thence is curved downward forward and ends in an upturned hook member 12, that is located between adjacent bristles 12 and may rest upon the free edges of the clamping-leaves 12. The length of thebrush-head is so proportioned that the brush proper will in length equal that of the width of the lower sash between its side members, and thus be adapted to have contact with the glazing of the sashes throughout their width when the brush is in position for service. The bracketpla'tes 12 are secured upon the lower edge of the lower cross-rail on the upper sash D by means of screws passed through perforations in said plates, and the length of the brush-head, together with that of the brush material, is such that the brush will have contact with the glass in the lower sash when the latter is raised from the window-sill.

It will be seen that the brush-head and brush proper from their position close the space between the lower railof the upper sash and the glass in the lower sash, so that insects will be Patent 1.
